However, their presence alone does not mean that a person definitely has MS. A doctor will need to conduct additional testing to determine the presence of MS. To test OCB levels, a doctor will need to perform a CSF oligoclonal banding test, which involves inserting a needle into the spine to collect CSF. The diagnostic process will also involve the doctor: If elevated OCB levels are present but a person does not fit the criteria for MS, a doctor will likely continue to search for the underlying cause. Oligoclonal bands. The presence of these immunoglobulins can indicate inflammation in the central nervous system (CNS), which can suggest that a person has multiple sclerosis (MS). Immunofixation can either reveal a normal pattern or identify a monoclonal protein or a polyclonal immunoglobulin pattern. Philadelphia, PA, USA: Elsevier Churchill Livingstone; 2008. chapter 87. Diagnosis of multiple sclerosis; especially useful in patients with equivocal clinical presentation and radiological findings. According to Mayo Medical Laboratories, this screen is positive in 70 to 80 percent of MS patients. Unconcentrated CSF and diluted serum are electrophoresed by isoelectric focusing. Isoelectric focusing with the IgG immunoblotting compared with high resolution agarose gel electrophoresis and cerebrospinal fluid IgG index. [12] an additional assay for the identification of IgD or IgE must be performed. J Neurol Neurosurg Psychiatry. 18008 Bothell Everett Hwy SE # F, Bothell, WA 98012. An oligoclonal band is a protein called an immunoglobulin. Their presence suggests inflammation of the central nervous system due to infection or another disease. Tietz Fundamentals of Clinical Chemistry and Molecular Diagnostics. This article discusses the link between OCBs and MS and what the testing involves. Abnormal CSF OCB patterns have been reported in 70% to 80% of MS patients. The procedure usually takes about half an hour. [1] In the former, the serum is applied to an agarose gel, and the negatively charged serum proteins move toward the cathode under the influence of an electric current. These conditions should be promptly diagnosed and treated. Unconcentrated CSF and diluted serum are electrophoresed by isoelectric focusing. Ann Clin Lab Sci. Ramakrishnan N, Jialal I.

Therefore, the International Myeloma Working Group Mass Spectrometry Committee created a set of recommendations for the evaluation of monoclonal proteins in multiple myeloma and related disorders, using mass spectrometry. Next, theyll apply a local anesthetic. What do Oligoclonal Bands CSF and Serum test results mean? The CSF sample is collected by a lumbar puncture or spinal tap. Only a small number of oligoclonal IgG bands in 7 of 10 CSF and serum pairs had identical isoelectric points and the same type of L chain. Abnormal CSF OCB patterns have been reported in 70% to 80% of MS patients. Oligoclonal bands are visible as an increased concentration of restricted bands of IgG after isoelectric focusing and immunofixation of IgG. The separated immunoglobulins (Ig) are visualized by an IgG immunoblot, and OCBs that are present in the CSF and not in the serum are reported. Oligoclonal band investigations requires both serum and cerebral spinal fluid (CSF). Please enable it to take advantage of the complete set of features! Unconcentrated CSF and diluted serum are electrophoresed by isoelectric focusing. Cerebrospinal fluid (CSF) and serum, collected at the same time, 0.5 mL cerebrospinal fluid (CSF) and 0.5 mL serum, Red-top tube or gel-barrier tube and plastic (CSF) tube, Plasma instead of serum specimen (since fibrinogen band may obscure the electrophoretic zone); serum and CSF not collected within eight hours of each other, Diagnose diseases of the central nervous system including meningitis, tumor, syphilis, and multiple sclerosis, Isoelectric focusing (IEF) and immunoblotting on agarose gel. Diagnostics (Basel). Arch Pathol Lab Med. What are considerations regarding immunofixation results in multiple myeloma, and what are the limitations of a 24-hour concentrated urine sample for immunofixation testing? CSF is used in the diagnosis of multiple sclerosis (MS) by identifying increased intrathecal IgG synthesis qualitatively (oligoclonal bands). Please enable it to take advantage of the complete set of features! Examining CSF and serum in parallel for OCBs of IgG provides more diagnostic information than examining CSF alone, and the latter is potentially misleading. CSF immunofixation that does not reveal oligoclonal bands is also considered normal. Oligoclonal bands If present in both, they may represent systemic infection, autoimmune disease, sarcoidosis or neoplasia. Your doctor may order this test if he/she suspects that you have multiple sclerosis. Once the required sample is collected, he/she will cover the site of puncture with a bandage. Management of clinically and radiologically isolated syndromes suggestive of multiple sclerosis. Pathol Biol (Paris). What conditions show oligoclonal bands in serum? This test has been cleared, approved, or is exempt by the US Food and Drug Administration and is used per manufacturer's instructions. Increased IgG production by the central nervous system is not specific for multiple sclerosis, but is an indication of chronic neural inflammation. In the first group neoplasia and peripheral neuropathies accounted for over 50% of the diagnoses, infections and systemic inflammatory disorders for 32%, and multiple sclerosis was diagnosed in only one case.

Theyll send the CSF to a laboratory for analysis. However, the presence of oligoclonal bands does not necessarily confirm the diagnosis, as other conditions can present with oligoclonal bands in the CSF. Efficacy and outcome of autologous transplantation in rare myelomas. OLIGOCLONAL BANDS - Chughtai Lab Oligoclonal bands: clinical utility and interpretation cues The oligoclonal band pattern is blurred when a concomitant inflammatory response causes increased protein leakage of plasma proteins into the CSF. and transmitted securely. allowed for additional confirmatory or additional reflex tests. If there are two or more oligoclonal bands present in your CSF with no corresponding bands in the serum, the result is considered positive. Since 80% of normal CSF protein is derived from serum, patients with serum monoclonal proteins may also have corresponding CSF bands.
